MICROANATOMY

Detailed explanation-1: -The rise in gonadotropins during puberty stimulates the ovary to produce estradiol, which is responsible for developing secondary sexual characteristics such as thelarche, growth of reproductive organs, fat redistribution to the hips and breasts, and bone maturation.

Detailed explanation-2: -Puberty begins when the gonadotropin-releasing hormone (GnRH) neurons of the hypothalamus secrete GnRH in a pulsatile manner. Pulsatile GnRH causes pituitary gonadotrophs to synthesize and release luteinizing hormone (LH) and follicle-stimulating hor-mone (FSH).

Detailed explanation-3: -The glands and organs that make hormones and release them directly into the blood so they can travel to tissues and organs all over the body. The hormones released by the endocrine system control many important functions in the body, including growth and development, metabolism, and reproduction.

Detailed explanation-4: -The thymus gland, located behind your sternum and between your lungs, is only active until puberty. After puberty, the thymus starts to slowly shrink and become replaced by fat.
